Application of Geophysical and Electromagnetic Method in Prospecting in Yinshanjiao Area
In order to prove the occurrence of underground lead-zinc ore body in Yinshanjiao area and facilitate the placement of borehole location,the ore body is measured by geophysical exploration IP and high-precision magnetic method.Eleven IP anomalies are identified by geophysical prospecting IP,and one anomaly is identified by high-precision magnetic method.By using borehole verification and combining with the electromagnetic characteristics of regional rock ore,it is proved that the lithology should be considered in the exploration of lead-zinc ore in Yangliugang formation by geophysical exploration IP.High-precision magnetic measurement can be used as a method to search for lead-zinc-silver polymetallic minerals in the carboniferous limestone and shale of Yangliugang formation.Drilling and high precision magnetic survey have obvious prospecting effect in the study area,and indicate the prospecting potential direction of the area.
